3 分析問題
很明顯是因為沒有訪問 MySQL 數據庫的權限,導致訪問被拒絕。
打開代碼一看,果然是這樣,代碼裡沒有提供訪問數據庫的賬號和密碼嘛
ds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource"); ds.getDriverProperties().put( "url", connectionURL != null ? connectionURL : "jdbc:mysql://localhost:3306/hibernate?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull" ); Properties dp=ds.getDriverProperties(); dp.put("driverClassName", "com.mysql.jdbc.Driver"); ds.setDriverProperties(dp);
4 解決問題
趕緊加上,問題解決 O(∩_∩)O~
... dp.put("user","root"); dp.put("password",""); ... ds.setDriverProperties(dp);
